Zusammenfassung:	FIELD: technological processes.SUBSTANCE: method includes burnishing and heating of inner processed surface. To increase quality of processed parts, heating of the inner processed surface is carried out before burnishing to 550-600°C, and the heated surface is burnished with a cooled burnisher. Heating of the inner processed surface may be carried out for depth of 2.5-5.0 mm.EFFECT: improved quality of processed parts.2 cl, 1 dwg Способ включает дорнование и нагрев внутренней обрабатываемой поверхности. Для повышения качества обрабатываемых деталей нагрев внутренней обрабатываемой поверхности осуществляют перед дорнованием до температуры 550-600°С и производят дорнование нагретой поверхности охлаждаемым дорном. Нагрев внутренней обрабатываемой поверхности могут осуществлять на глубину 2,5-5,0 мм. 1 з.п. ф-лы, 1 ил.
